TIG filler rod is a solid welding rod used in Gas Tungsten Arc Welding (GTAW), commonly known as TIG welding.
Unlike consumable wire processes, TIG welding uses a non-consumable tungsten electrode to generate the arc, while the filler rod is manually added to the weld pool. This allows precise control of heat input and weld quality.
TIG filler rods are widely used for thin-wall materials, pipe welding, root pass welding, and applications requiring superior weld appearance and mechanical integrity.
We manufacture nickel alloy and stainless steel TIG filler rods for high-performance industrial environments.

TIG filler rods are commonly used in precision welding applications requiring clean weld appearance and superior mechanical performance.
They are widely applied in pipe welding, aerospace components, pressure vessels, and high-purity systems where weld quality and corrosion resistance are critical.
Nickel alloy TIG filler rods are particularly suitable for high-temperature service environments and dissimilar metal welding.
TIG welding
application
Ø Use high-purity argon shielding gas
